Michel de Montaigne's Complete Essays Collection

Michel de Montaigne (February 28, 1533 – September 13, 1592) was one of the most influential writers of the French Renaissance, known for popularising the essay as a literary genre, and commonly thought of as the father of modern skepticism. He became famous for his effortless ability to merge serious intellectual exercises with casual anecdotes and autobiography—and his massive volume Essais (translated literally as "Attempts" or "Trials") contains, to this day, some of the most widely influential essays ever written.
